The epidermal growth factor receptor (EGFR) family plays an important role in colorectal cancer (CRC). EGFR participates in the key process of tumorigenesis and invasion, and its expression correlates with the prognosis of CRC. EGFR-targeted therapy has been widely utilized in stage III and IV CRC. The EGFR antibodies, cetuximab and panitumumab, are widely used in treatment of CRC. There are clinical trials and in vivo studies being carried out on the efficacy and mechanism of their action in CRC treatment. In this review, we will describe the EGFR-targeted therapy used in CRC, focusing on the efficacy and mechanisms of the most commonly used EGFR antibodies, cetuximab and panitumumab.
